S-90395A339 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• High-strength thread forming design creates secure, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Optimized for sheet metal applications with a 0.242" thread diameter and 10 threads per inch, ensuring reliable fastening in materials up to 0.025" thickness.
• Easy installation and removal with a No. 3 square drive and pan head design, providing excellent torque transmission and driver bit engagement.
• Full 2-inch threading offers maximum grip length and load distribution, preventing loosening under vibration and stress.
• Compliance with international environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries and global supply chains.
• Versatile right-hand thread and pointed tip enable quick starting and straightforward alignment in assembly operations.

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws are engineered specifically for sheet metal applications, where traditional fasteners often strip or fail under dynamic loads. The thread forming technology displaces material to create strong, clean threads without generating chips, eliminating contamination risks in electrical enclosures, HVAC systems, and automotive assemblies. The zinc plating provides a durable barrier against rust and corrosion, crucial for outdoor or high-moisture environments. With a pan head and square drive, these screws withstand high torque during installation, reducing the risk of cam-out and ensuring consistent clamping force. Ideal for construction, metal fabrication, and industrial maintenance, they deliver reliable performance where vibration resistance and long-term integrity are paramount.

Specification Summary & Compliance

This thread forming tapping screw conforms to Type A/AB standards with a 0.242" thread diameter and 10 threads per inch, manufactured to precise dimensional tolerances for consistent performance. The fully threaded 2-inch length and pointed tip facilitate easy penetration into pre-drilled 5.5 mm (0.2165") holes. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to strict environmental and safety standards, making these screws suitable for global industrial and commercial use without hazardous substance restrictions.
